About Stephane

I am a passionate senior expert in high technologies & TechLead – Mobile, specializing in system & infrastructure or application architecture (Linux / Unix / Solaris), as well as expertise in virtualization, storage, and Disaster Recovery. With over 20 years of experience, including 10 years at Thales Global Services, I have earned a solid reputation as a reliable and high-performing expert, capable of tackling the most critical challenges. I have deployed numerous infrastructures in confidential environments for renowned companies such as GEMALTO, IBM, and ATOS.

For me, teamwork is a fundamental pillar. Knowledge sharing is at the very heart of our professions. While the adage "All for one and one for all" is often cited, I prefer to say: "The more, the merrier." A good leader must unite, bring together, and protect their team to ensure its success.

In my work, I distinguish myself by a deep commitment to excellence and success. I place paramount importance on precision, meeting deadlines, and achieving set objectives.

Failure and delays are, for me, eventualities that I strive to prevent at all costs. This philosophy leads me to anticipate, plan rigorously, and invest myself fully in every project. Every challenge is an opportunity to prove my determination and my ability to find solutions, even in the most complex situations.
